It depends what important means. In terms of contributions to the modern world, Ancient Greece contributed to Medicine, Science, Art, Engineering and Philosophy and laid the foundations of the Renaissance. However, the Golden Age of Ancient Greece has roots in ancient Egypt. Rome was an outstanding military force but it's contributions to Art and Science are disproportionate to that of Greece and it is generally considered to have stalled advancements in these areas by conquering the Hellenic world. However the Romans had a contribution in Engineering. The Arabs took over Greece in Mathematics and advanced algebra. It really depends what you consider important. Important in what field? In terms of science and technology I would have to go with Greece.
This answer depends on what successful means. If it means how long it lasted, then China is the most successful civilization following by the Byzantine empire. In terms of contributions to science, medicine, philosophy and the arts the Hellenic civilizations are the most successful. In terms of expansion, Rome, Mongol empire and more recently Britain were the most successful. I go with Greece cause I'm a science person.
